This gearmotor is a miniature (0.94" x 0.39" x 0.47"), low-current brushed DC motor with 30:1 metal gearbox, similar to Sanyo's popular 12 mm gearmotors. These units have a 0.365"-long, 3 mm-diameter D-shaped output shaft. This version also has a 4.5 x 1 mm extend...

This gearmotor is a miniature (0.94" x 0.39" x 0.47"), low-current brushed DC motor with 50:1 metal gearbox, similar to Sanyo's popular 12 mm gearmotors. These units have a 0.365"-long, 3 mm-diameter D-shaped output shaft. This version also has a 4.5 x 1 mm extend...

This servo rotates fully forward or backwards instead of moving to a position. You can use any servo code, hardware or library to control these servos. Good for making simple moving robots. Comes with one horn only, as shown

Move fluid safely from here to there with this very nice little pump. Unlike most liquid pumps, this is a peristaltic type - the pump squishes the silicone tubing that contains the liquid instead of impelling it directly. The upshot? The pump never touches the flu...

This custom-designed white plastic wheel has a rubber tire measuring 1.65" (42 mm) in diameter and is designed to fit the output shafts on our micro and 15.5D metal gearmotors as well as the Solarbotics metal gear motors. Teeth on the hub optionally allow a reflec...
